Icelandic horses are a special breed of small horses well known for their spirited temperaments. According to Wikipedia, they have few diseases in their native country and were developed from ponies taken to Iceland by Scandinavian settlers in the 9th and 10th centuries. The ones that we saw (when our driver stopped by the roadside for us to take a look at them) were certainly tame, even in the half-blizzard that was brewing!
